Answer:
21
Step-by-step explanation:
f(x) = 2x^2 + 3
f(-3) = 2(-3)^2 + 3
f(-3) = 2(9) + 3
f(-3) = 18 + 3
f(-3) = 21
Answer:
1.25
Step-by-step explanation:
3.75 divided by 3 = 1.25
Our angle teta is:
teta = 3pi/4
since that is larger than pi/2 but less than pi that means that our angle lies in II quadrant (x negative y positive)
sin(3pi/4) = √2/2
cosine and tangent of that angle must be negative because of position of the angle.
cos(3pi/4) = -√2/2
tan(3pi/4) = -1
Answer:
a , c , b
Step-by-step explanation:
just input the numbers in a TI 84 calculator (if you don't have I would be happy to show you how to download the free online version.) And sort from greatest to least.
It has to be 5 because 2.5 is half so the other half 2.5 .so 2.5 +2.5 =5
